SIPHON-HEAD FOR BOTTLES.

Application filed October 21, 1913.

To all whom it may concern:

Be it known that I, ALEXANDER P. MARA, subject of the King of Great Britain, residing at St. Louis, in the county of St. Louis, State of Missouri, have invented certain new and useful Improvements in Siphon-Heads for Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention is directed to improvements in siphon heads for bottles, and has for its object to so construct a device of this character that the same can be readily attached to or removed from the neck of a bottle.

A further object of the invention is to provide a device of this character so con structed that it will be thoroughly sanitary, and further to produce an article so constructed that the expelled liquid will not come in contact with the metal, as is the usual practice in siphon heads of the ordinary construction.

With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the device. Fig. 2 is a vertical sectional view through the same. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is a similar view on line 44 of Fig. 2.

Referring to the drawing, the numeral 1 designates the bottle, and 2 the neck thereof, said neck having its upper end provided with an. annular shoulder 3. Engaged around the neck 2 is a sectional sleeve 4, the upper edge of which engages the shoulder 3, thus preventing movement of said sleeve. The sleeve 4 is exteriorly threaded, as at 5, for engaging the interior threads 6 of the sleeve 7 which is formed from metal, as is the sleeve 4. The sleeve 7 is provided with an annular shoulder 8, said sleeve being passed through the central aperture 9 of the disk 10, the shoulder 8 serving to prevent disengagement of the disk 10 in one direction. The disk is provided with a vertical annular flange 11 which is threaded, as at 12, for engaging the threads 13 formed exteriorly upon the lower end of the sectional metallic casing 14, said casing also having Specification of Letters Patent.

its upper end exteriorly threaded, as at 15. The sleeve 7 has its upper end terminating in an annular flange 16, which forms a seat 17 which is engaged by the annular rim 18 formed upon the lower end of the porcelain or glass cylinder 19, said rim forming an annular shoulder 20 which engages the upper edge of the flange 16. Arranged between the lower face of the rim 18 and upper edge of the bottle neck 2 is a rubber disk 21, which rests upon the cork washer 22, said disk and washer being provided with central apertures 23 and 24, respectively, in which is engaged the upper end of the siphon tube 25, the upper end of which projects beyond the upper surface of the disk 21, and enters the bore 26 formed in the lower end of the cylinder 19, said bore opening into the passage 27, which is smaller in diameter than the bore 26 so that an annular shoulder 28 is provided which will limit the movement of the cylinder in one direction.

The upper end of the cylinder 19 is provided with an annular groove 29 which has opening thereinto the discharge passage 30 of the spout 31 which is formed integral with the cylinder 19 and projects through the opening 32 formed in the sleeve 14, and at a point where the edges of the sections forming said sleeve meet. By providing the annular groove 29 avalve seat 33 is provided, said seat being normally engaged by the rubber valve disk 34, the lower edge of which engages the annular rim 35 formed upon the upper end of the cylinder 19, and is retained in place by the lower end of the metallic cap 36, said cap having its lower end provided with an annular flange 37 which engages in the annular groove 38 formed by the cylinder and upper end of the casing 14. To retain the cap 36 in place, and thus the valve disk 34 a flanged nut 37 is provided so that its interiorly threaded flange 39 will engage the threads 15 formed upon the upper end of the casing 14.

The valve disk 34 is provided with a socket 40 which is engaged by the head 41 formed upon the lower end of the metal plug 42, said plug having its upper end engaged by the lower end of the coil spring 44, the upper end of which engages the inner surface of the top of the cap 36. To center the spring 44 the plug 42 is provided with an extension 45. The plug is provided with a slot 46 which is engaged by the inner end of the lever 47, said lever being pivotally connected to the cap 36 in any suitable manner, so that its outer end will be conveniently located for engagement by the operators thumb. It is obvious that upon pressure being applied to the lever 47 that the plug 42 will be raised, likewise the valve disk 424:, thus per-a mitting the liquid to be discharged through the valve seat 33 and spout 31.

From the foregoing description it will be seen that a siphon head has been provided which can be easily and quickly applied to a bottle, and when placed thereon the liquid during its discharge will not contact with the metal.

What is claimed is 2- The combination with a bottle provided With a neck having a shouldered upper end; of a sectional sleeve embracing said neck below said shoulder, a second sleeve screwed on the first mentioned sleeve and provided with ,ashouldered upper end, a disk surrounding said second sleeve and engaging beneath the shoulder thereof, a threaded flange formed on said disk in spaced relation to the upper portion of the second sleeve at the shoulder thereof, a tube secured between said flange and second sleeve, said tube being screwed into said flange, a valve mechanism held within said tube, and a flanged nut screwed on the upper end of said tube to hold said valve mechanism in position.

In testimony whereof, I affix my signature, in the presence of two witnesses.
